After more than two years of development, Xfce 4.4.0 has just been released. Xfce 4.4 features new tools such as the much awaited Thunar file manager as well as several improvements in its core components.
Benedikt Meurer had also prepared a tour for the newcomers.

I've been running a SVN build (out of the archlinux unstable repo) for some time, since some of the 4.4 features are enough improved (in my opinion) to make it worth the hassle. Its been as stable as anything, and impressively fast since I started. I spent about a week fiddling whatever bothered me (you really can tweak every behavior in a fairly straightforward way) and it looks and feels entirely "natural" to work in. (Currently using Candido-Redux theme with Etiquitte-xfce icons with it, just to plug since I'm pleased with them.) Highly recommended, especially for the new tabbed terminal emulator and Thunar. Only feature I like but haven't been able to play with is transparency since the fglrx drivers don't play nice with compositing.
